LOL I ordered that this morning before running out the door to work. It's already shipped (no pun intended!) After one hour cruising with my first r/c boat (a springer) i'm hooked but good. I just bought enough 1.5, 3, and 6mm ply for two boats. I'll be sure to log this build and I will publish the plans when its complete.

As this tug is for my wife we will have a design consultation soon to settle some details about the wheelhouse and color scheme.

It seems to me that you want to make the drive system very complicated.
You can use a straight drive line at an angle. This is the same method that full size use.
I am building a class A hydro plane that has a flat bottom. These are normally powered with an out board. I am using a inboard drive with a dummy outboard.
Nice and simple

Model ?

being an airplane guy I have to ask, whats the effect of the down-thrust? does it even matter to the handling? and is my straight drive really complex? I just think a flat bottom seems too easy to build to really work well.. the box keel seems more of a midway between a real V-type hull and a flat bottom. AND it stands up on the shelf without a cradle.

Neat looking design! I like your straight drive line approach- I think it would work very well for this boat. Flex-drive, which was suggested has one disadvantage in that it does not like to go in reverse all that well.

The down thrust has very little effect. If it did there would be a lot of full size boats in trouble. Almost all boats have a down trust unless they use and outboard, stern drive, or have a very deep hull. Just take a look at all the inboard sport boats.
I went this way in the hydro so I could put a larger and faster motor in. The original 3 point hydro's were set up this way, now most use surface props, but the shaft still has an angle to it.
Kap is right a flex drive dose not work well in a scale boat. In reverse the cable can unwind and can also pump water into the boat.
Of my 105 running boats I think that about 85% have the shafts at an angle.www.jsgill.net
By the way I also fly only 54 aircraft.

Here is another option, this is the same company that I used for the Dipper 19 build using their plans. For $1.00 you can download the study plans or go to his website to see what else he has to offer. (http://store.devlinboat.com/godzilla...samerican.aspx ). Jerryj98501

I came up with three concepts for the wheelhouse, and let my wife choose the shape, smokestack, and color scheme. Since this is the first R/C hobby she has wanted to get into, I'm building this boat for her.
